Dynamic Rectifier Control / Dynamic Efficiency Scaling
V-rect is the voltage controlled by the global feedback loop, it is LDO input. The Dynamic Rectifier Control
algorithm will adjust this voltage based on output current. The Dynamic Efficiency Scaling will adjust V-
rect based on max output current set by R I-lim. The below graph show effect of both features on V-rect
with three different values of R I-limit.
